Figure 2.
Results from Experiment 1. (a) Mean error rate (proportion), (b) mean RT (ms), (c) mean number of fixations, and (d) mean fixation duration (ms), for correct and incorrect responses for each of the prevalence and target presence conditions, plotted by set size. Error bars represent within-subjects 95% confidence intervals. Note the fixation data are from search fixations only (excludes the initial central fixation for all conditions and the target fixation for target-present trials). HP = high (50%) prevalence, LP = low (2%) prevalence.
